Abstract

A device for calibrating two electric motors mounted on one axle in two-axle motor vehicles includes at least one electronic control unit configured to check whether predefined conditions for a switchover from torque control to rotational speed control are met. If met, the at least one electronic control unit is configured to switch to rotational speed control for a predefined period of time. A torque-dependent characteristic map with correction values is created on the basis of this difference. The target torques are corrected by the correction values during torque control after rotational speed control has been deactivated.
